A growing body of literature has highlighted the importance phytoplankton-bacterial associations to marine and estuarine ecological biogeochemical function, but their population linkages remain sparsely characterized within urban estuaries. Since many developed coastlines are heavily impacted by anthropogenic nutrient inputs, elucidating dynamics provides insight into cycling, productivity, can help inform water quality management. This study compared surface (0.5 m depth) physical quality, cell abundances major phytoplankton taxa bacteria, as well concentrations chlorophyll a (chl ) dissolved organic matter (DOM) in nitrogen (N)-enriched Western Long Island Sound (WLIS), USA, between mid-channel shore sites (in 2020 2021). Shore bacterial DOM (primarily N carbon [DOC]), were significantly higher than mid-channel, especially during summer, indicative terrestrial loading influencing microbial assemblages C cycling. Abundances key better indicators chl , positively correlated with those dinoflagellates, most common genera Prorocentrum (mid-channel, shore) Heterocapsa (shore only), not diatoms. However, pennate diatom negatively DOC mid-channel. Results highlight impact inputs on WLIS assemblage dynamics, presumably favoring bacteria dinoflagellate coupling, shed new how communities respond loadings
